Product Overview
This Specpure® lead plasma standard solution delivers exceptional purity and accuracy for demanding analytical applications. Formulated at a concentration of 10,000µg/ml in a stabilized nitric acid matrix, it ensures minimal matrix interference and long-term stability. The solution is manufactured under stringent ISO 9001 quality controls, with each batch traceable to NIST reference materials for guaranteed reliability. Its ultra-low impurity profile (<10 ppb for most trace metals) makes it particularly suitable for ultra-trace analysis in environmental monitoring, metallurgical assays, and advanced research applications. The solution comes in amber glass bottles with tamper-evident PTFE-lined caps to prevent contamination and degradation. Compatible with all major ICP-OES, ICP-MS, and AAS instruments, this standard eliminates the need for in-house preparation while providing consistent, reproducible results. The extended shelf life of 24 months when stored properly at 15-25°C makes it a cost-effective choice for laboratories requiring frequent calibrations.
FAQs
1. What is the exact matrix composition of this lead standard solution?
The solution is prepared in a 2% nitric acid matrix using ultra-pure reagents, with residual acidity carefully controlled to maintain stability without interfering with most analytical techniques.
2. Can this standard be used for mercury analysis as well?
While optimized for lead determination, the ultra-low mercury content (<0.5 ppb) makes it potentially usable as a matrix for mercury analysis, though dedicated mercury standards are recommended for optimal accuracy.
3. What certification documentation is provided with each bottle?
Each unit includes a comprehensive Certificate of Analysis detailing the exact concentration, uncertainty values, traceability information, and batch-specific impurity profile.
4. How does the packaging prevent contamination during storage?
The amber glass bottles block UV light while the PTFE-lined caps create an inert barrier, with each bottle individually sealed and nitrogen-purged to minimize oxidative degradation.
5. What’s the recommended procedure for preparing working standards from this concentrate?
Serial dilution using 2% nitric acid as the diluent is recommended, with thorough mixing at each step to maintain homogeneity, particularly when preparing standards below 100 ppb concentration.
